Hi all. My first post, so bare with me if I'm asking the wrong forum. I run my own 'one man band' business designing and installing ropes courses and climbing towers using wood and steel. I'm not a designer or engineer! I liaise with clients then employ structural engineers and specialist fabricators. Could anyone suggest the most appropriate software to use to create basic 3D illustrations which I can use to illustrate the structure / shape / layout for my clients at the quotation stage. These will have the same components but they overall structure will be different for each client, maybe even 2 or 3 different options. I do not need to detail every nut and bolt or be able to send perfect 'designs' to engineers / fabricators. Just professional looking 3D illustrations for potential clients. As a 'one man band' I need to be able to do quickly and cost effectively each time, whilst running all the other parts of my business.
